My fault. The beta ISO ships with 2.6.17-10-generic yet LTSP builds with 2.6.17-10-386 and couldn't find the necessary USB modules. apt-get update the LTSP server, manually select the 386 kernel and things work correctly.
Wacom USB works, tablet functionality requires dexconf changes and installation of wacom-tools. Case closed. ** Changed in: wacom-tools (Ubuntu) Status: Unconfirmed => Rejected -- Edgy: wacom tools break USB keyboard/mouse https://launchpad.net/bugs/65004 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
